UN Physics Magnetic Field Mutual Inductance M of Two Coils Question

A current I circulates through a straight solenoid of length “a” formed by N circular turns of area S. Draw a clear diagram of the situation and calculate:a) the magnetic flux that crosses one turn.b) the magnetic flux that crosses the set of turns.c) the inductance of the solenoid.Then, on this same solenoid, a second solenoid of length “a” and N’ circular turns of area S’S is wound coaxially. Determine in this situation the mutual inductance M of the two coils.
